Is it natural to laugh in a situation like this? Probably not, as it is an intense emotional scenario. The couple’s words can have a long-term impact on their children. Are there those that will laugh? Yes. Sometimes it is an emotional reaction to a stressful situation. Another, and it sounds like this might be your case, is that you are able to step away from the anger being displayed and look at the bigger picture. The topic of the argument is just plain silly.
